Application Number: JP,2022-184108
Category (FI): H02G15/18,H02G1/14
Stage: PROBLEM TO BE SOLVED: To provide a wire connection metal fitting capable of facilitating a positioning of an electric wire when connecting a thick diameter electric wire, and an adjustment of an insertion depth of the electric wire, preventing an increase of an electric resistance value by a secular use, suppressing a temperature increase of the electric wire to be connected, and securing a safety.SOLUTION: A wire connection metal fitting is constructed so that a center stopper metal washer 3, a coil spring 4, a coil spring metal washer 5, and a collet 6 are assembled so as to be inserted from an open part 2a to a cylinder-shaped main body center part 2, after that, a cylinder-shaped main body end part 7 is screwed with a female screw part 2e and a male screw part 7e to be detachably attached to the main center part. The main center part includes: a connection hole 2b communicating the open part of both ends; a center stopper part 2c of an intermediate position of the connection hole; a drain hole 2d penetrated to an inner peripheral surface from an outer peripheral surface; and a female screw part 2e which is near from the open part. The main body end part includes: an electric wire insertion inlet 7a; an electric wire insertion export 7b; a projection part 7d; an insertion hole 7c communicating the electric wire insertion inlet and the electric wire insertion export; and a male screw part of the outer peripheral surface of the projection part.SELECTED DRAWING: Figure 1 (Grant)
